As many Chilean alstroemerias, this is a very beatiful flower. It has the advanatage that it grows low, and is ideally suited for potting, although of course it can be grown outside. The place where it grows is covered with snow for more than 4 months and - 10º C is frequent here" It needs loose, poor soil with good drainage and moderate watering.
The easiest form to germinate this species is to plant it in autumn and expose the seeds to natural temperature fluctuations. If you decide to do it "scientifically," soak the seeds for a day or so in water, then put them into wet sand and put them into refrigerator at about +2 +5º C for about 30 days. Allow the seeds to breathe (ventilate from time to time) and check the humidity of the sand (it tends to dry out quickly, so adding moisture every three-four days is a must). Then take them out and plant at room temperatures. If not all seeds or few seeds germinate, repeat the cold step once more. This plant needs good drainage and relatively poor soil.
